This novel is great until the 5th Volume started.Writing Style: 4/5The author is fluent in English, though occasionally making typos here and there. He has a good writing style, not seeming to break the immersion. My only real problem is the paragraph structure wherein paragraphs get too long.World Background: 4/5Background is great and well thought out. My only surprise is the mention of Mana reservoirs, seemingly unfitting for a life in modern society. There are also some inconsistencies in the world building here and there.Character: 3/5The characters would have been a 4/5 if not for Volume 5. Each character has their own unique personality. Though some like Noah were introduced abruptly, this was at the beginning segments. One character that was special was Luna. She was one of the genuinely interesting characters. She unlike the other girls had a genuine affinity with the MC. Unfortunately, the author decided to separate her in the name of Character Progression, which I disagree with. If not for what the author decided to make her do in Volume 4 and what was evident during Volume 5, I would have rated this a 4 or even a 5.Story: 2/5Same problems with the Characters segment. Vol 1 was consistent while Vol 2 was amazing. The ending was great. Honestly, the story could've ended there with my review on this with 4 for chara, 5 for story and even 5 for world, since inconsistencies started with Vol 4. Unfortunately, the author didn't seem to know that everything wouldn't change with 1 conversation. But it did and now the joy of reading this story is lost.All in all, I'm dropping. The story doesn't have a lot of clichés but because of that, the story gets unnatural in parts where clichés naturally occur. I hope the author learns from this review.
